One of the most common misunderstandings in pension fund land is that an individual (member) investment policy weighs up to a collective investment approach.

Is there a rule of thumb that expresses 'longevity risk' in terms of the yearly return?

1. Collective vs. Individual Investing Approach

In case of a 'healthy pension fund', new members will join as time continues. In a mature pension fund the balance of contributions, investment returns, paid pensions and costs will stabilize over time.

Therefore the duration of the obligations of a pension fund will more or less stabilize as well. The duration of an average pension fund varies often between 15 and 25 years. Long enough to define a long term investment strategy based on a mix of risky equities (e.g. 60%) and fixed income (e.g. 40%). Regardless of age or status, all members of a pension fund profit from this balanced investment approach.

In case of an individual (member) investment strategy, the risk profile of the individual investments has to be reduced as the retirement date comes near. In practice this implies that 'equities' are reduced in favor of 'fixed income' after a certain age. As the age of a pension member progresses, the duration of the individual liabilities also decreases, with an expected downfall in return as a consequence.

Let's compare three different types of investment strategies to get a clear picture of what is happening:

Now lets compare the pension outcomes of these three different investment strategies with help of the Pension Excel Calculator on basis of the next assumptions:

- Retirement age: 65 year

- Start ages 20 and 40

- 3% and 0% indexed contributions and benefits

- Life Table NL Men 2012 (NL=Netherlands)

Results Pension Calculations (yearly paid pension):

Conclusion I

From the above table we can conclude that switching from a collective investment approach to an individual investment approach will decrease pension benefits with roughly 10%. Think twice before you do so!

2. Longevity Risk Impact

To get an idea of the longevity impact on the pension outcomes, yearly paid pensions are calculated for different forecasted Dutch life tables (Men).

Life Tables

Forecast Life Table 2062 is calculated on basis of a publication of the Royal Dutch Actuarial Association.

The Forecast Life Table 2112 is (non-official; non scientific) calculated on basis of the assumption that for every age the decrease in mortality rate over the period 2062-2112 is the same as over the period 2012-2062.

Pension Outcomes per Life Table

Here are the yearly pension outcomes on basis of the forecasted life tables:

From the above table, we may conclude that the order of magnitude effect of longevity over a fifty to seventy year period is that pensions will have to be cut roughly by 25%-30%.

Another way of looking at this longevity risk, is to try to fund the future increase in life expectation from the annual returns.

The next table shows the required return to fund the longevity impact for different forecasted life tables:

Roughly speaking, the expected long-term longevity effects take about 0.7%-1.2% of the yearly return on the long run.

Finally

Instead of developing a high tech approach, this blog intended to give you some practical insights in the order of magnitude effects of life-cycle investments and longevity impact on pension plans in general.

The current definition of Public Debt is very poor. Only accrued past debt and current budget deficits are measured; no future obligations.

Hot from the press, the 'actuaries' behind the 83rd BIS Annual Report 2012/2013 show us the impact of the commitments to future spending on pensions and health care that are missing in current measure of public debt.

Age-related liabilities as a share of GDP, are projected to rise considerably between 2013 and 2040 in a number of countries.

Please notice that reforms enacted after December 2011, are not included in the next graph.

Actual Public Debt
End 2012, the impact of age-related liabilities on the actual public debt was calculated and analyzed by Stiftung Marktwirtschaft, in cooperation with the Research Centre for Generational Contracts.

In a report called "Honorable States? The Sustainability of European Public Finances in Times of Crisis" they calculated the effects for Europe as follows:

Reforming Social Security
Without going into details, this graph makes perfectly clear that even an attitude of 'just managing debt' is hopeless and doomed to fail.

'Restructuring public debt' will only be possible if we have the courage to fundamentally restructure our social security system of pensions and health care. The sooner, the better.....

For those who still had hope on a positive U.S. outcome, just take a look at the debt-outcome of two non-EU countries:

Concluding Reflections
To get a sound picture of a country's financial sustainability, a first step would be to annually report real(istic) balance sheets on basis of actuarial public debt, e.g. debt including age related future obligations like state pensions and health care.

Ultimate, we need new market value based 'country state accounting principles' that include a complete set of "future obligations" and "natural resources" (oil, gas, water power, etc.) on the asset side.

One of the main issues will be how to value a virtual and information society including fast changing and new future developments on basis of outdated valuation methods, developed in last decades of the last century.

Of course THE big challenge with such an ultimate country balance sheet will be how to value "human resources" as an asset. Why?

Because flexibility, responsiveness, education and entrepreneurship will eventually make the big difference in adapting a country's economy to a sustainable future. I suggest we start by valuing actuaries ;-).

The Pope, a well seasoned actuary and a student nurse are flying on an airplane. The captain comes back and says that he has some bad news and some really bad news. The bad news is that the plane is going to crash! As he puts on a parachute and jumps out he says that the really bad news is that there are only 2 more parachutes.

The actuary says: “I am the smartest man in the world. I've just calculated my life expectancy to be more than fifteen years. Excuse me...” With that he puts on a parachute and jumps out.

The Pope says: “Well, my child, I would love to live, but I believe that my time is up. Please take the other parachute and save yourself.”

The student nurse says: “Not to worry Holy Father. Right now the smartest man in the world is trying to find the rip-cord on my back pack!”

In 'The Actuary June 2010', Greg Becker (actuary) and Arminder Kainth (annuities pricing analyst) present the outcome of an actuarial model they developed, to predict the probability of a country winning the Fifa World Cup 2010.

With Brazil as a clear winner, here's the outcome:

Perhaps trading on the World Cup 2010 Bet Market can become a new interesting alternative for traditional investment categories....
Anyhow, let's hope (fingers crossed) that actuaries are right and Brazil, Germany, Italy and England all end in the semi-finals. In this case we'll ask both actuarial whiz kids to develop a new actuarial investment model to settle (for ever!) the everlasting bonds-stocks discussion....

Actuarial ModelsCollective (organizing) mechanisms are important stuff for actuaries. For example, they play an essential role with regard to all kind of solidarity aspects in pension- and insurance-contracts.

Moreover, collective rational or even emotional behavior often plays a decisive role in our society, as may be clear from the 2009 credit crisis turmoil and the escalating bonus madness.

Be aware, study "collective behavior mechanisms" and take them into account when you set up your actuarial risk model.

Enhance transparency of the actuary’s conclusions by identifying differences between the “best estimates” of management and the actuary.

Enhance the public’s understanding of actuarial estimates and to refine actuarial methodologies.

To improve the transparency of actuarial estimates by providing the changes from one reporting period to the next within the actuarial report.

To enhance the quality of corporate governance for property/casualty insurers by educating audit committees and/or boards of directors on the roles and responsibility of the appointed actuary.

To enhance self-governance of the actuarial profession with respect to reserve opinions by requiring the appointed actuary to provide an explanatory document with the ABCD whenever the change in the actuary’s reserve estimate over a defined period of time exceeds certain predetermined thresholds.

Incorporate the actuarial statement with the Jurat page of each property/casualty insurance company’s Annual Statement.

These recommendations could also apply to non-casualty actuarial areas.
